A really good burger has to be made from really good beef. If you can, ask a butcher to mince some rump, blade or chuck steak for you, but make sure it has 20 per cent fat content, as in effect this will make them self-basting and will prevent them from drying out during cooking. Otherwise, buy ordinary minced beef from the supermarket, but don't buy extra-lean mince or the burgers will become tough during cooking.

Farmed salmon has become much better quality over the years, and in my opinion some of the best available comes from Ireland, where the sea is always freezing cold and for the most part is unpolluted, with strong tidal flows. Make sure your salmon fillets are all even-sized and about 2.5cm (1in) thick to ensure even cooking. They also work well on the barbecue and can be made up to 12 hours in advance, covered with clingfilm and chilled until needed - just don't add the squeeze of lemon juice until you're ready to cook them.

Rozanne says: "This is my mom's recipe and it is the easiest, most decadent chocolate pudding. It is like a giant chocolate fondant baked in a lasagne type dish. There are two parts to the recipe, a sponge batter and a sauce. These get made separately and then poured into the dish. They curdle and look strange, but during baking they separate and you get chocolate sponge on the top and a rich dark chocolate sauce underneath. Serve warm with cream or ice cream and fresh or frozen berries.
Some of the solid ingredients are measured by volume in millilitres, so use your measuring spoons for small amounts and your measuring jug for larger quantities."

Rozanne says: "Anchovies can be bought in tins or glass bottles, preserved in salt and oil. They are an indispensable Pantry Pal in Italian cooking. They melt into dishes, imparting a rich, salty, savoury flavour. Don’t be put off, as they aren’t fishy and really work like a condiment. Be brave – try them!
My dad is a pro at barbecuing, especially lamb. This may look like a large, daunting piece of meat, but it’s actually very simple to cook and a hassle-free way to feed a crowd. The marinade and salsa are based on classic Italian flavour combinations and always work."
